使用jQuery操縱表格-增加、刪除行和列，示例代碼如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<style type="text/css">
.cl1{
background-color:#FFFFFF;
}
.cl2{
background-color:#FFFF99;
}
</style>
<script type="text/javascript" src="css_js/jquery/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
var rowCount = 0;
var colCount = 2;
function addRow(){
rowCount++;
var rowTemplate = '<tr class="tr_'+rowCount+'"><td>'+rowCount+'</td><td class="cl1">內容'+rowCount+'</td><td class="cl1"><a href="#" οnclick=delRow('+rowCount+')>刪除</a></td></tr>';
var tableHtml = $("#testTable tbody").html();
tableHtml += rowTemplate;
$("#testTable tbody").html(tableHtml);
}
function delRow(_id){
$("#testTable .tr_"+_id).hide();
rowCount--;
}
function addCol(){
colCount++;
$("#testTable tr").each(function(){
var trHtml = $(this).html();
trHtml += '<td οnclick="delCol('+colCount+')">增加的td</td>';
$(this).html(trHtml);
});
}
function delCol(_id){
$("#testTable tr").each(function(){
$("td:eq("+_id+")",this).hide();
});
colCount--;
}
function mover(_id){
$("#testTable tr:not(:first)").each(function(){
$("td:eq("+_id+")",this).removeClass("cl1");
$("td:eq("+_id+")",this).addClass("cl2");
});
}
function mout(_id){
$("#testTable tr:not(:first)").each(function(){
$("td:eq("+_id+")",this).removeClass("cl2");
$("td:eq("+_id+")",this).addClass("cl1");
});
}
</script>
